APPARATUS FOR COOLING FLIDS.

Specification of Letters Patent.

Patented J an. 2, 1912.

Application filed February 20, 1911.. Serial No. 609,786.

To all whom it may concern:

Be it known that 1, Louis RUTHnNURe,

a citizen of the 'United States, residing at Louisville, in the county of Jefferson and State of Kentucky, have invented certain new and useful lmprovements in Apparatus for Cooling Fluids, of which the following is a specification. A l

My invention relates broadly to an apparatus for cooling iiuids and more particularly to such apparatus for cooling water and other tluids serving to keep the cylinders and other parts of an internal combustion engine, at a requisite temperature.

An important objectl of this invention is to provide an apparatus of the above chan acter, so constructed that the fluid to be cooled is passed through means having a very large radiating surface, and such means having said radiating surface subjected to large quantities of a cooling medium.

A further object of this invention is to,

provide apparatus of the above character, comprising tanks to hold the fluid to be cooled and after cooling, respectively, a plurality of tubes for establishing communication between the tanks, and means for forcing air radially between the tubes.

It further object of this invention is to provide a cooling apparatus of the above char-act r which is simple in .construct-ion, cheap to manufacture, and not subject to derangements.

A further object of this invention is to provide a novel central support for the tanks and the rotatable fan disposed therebetween.

@ther objects and advantages of this invention will be apparent during the course of the following description.

In the accompanying drawings forming a part of this specification, and in which like numerals are employed to designate like parts throughout the same, Figure 1 is a front view of my cooling apparatus, parts thereof being shown in vertical section, and Fig. 2 is a side view of the central. support and associatedv members.

In the drawings wherein is illustrated a preferred embodiment of my invention, a cooling apparatus is shown, comprising upper and lower tanks 1 and 2 formed of pairs of tank sections 3 andft, respectively. The

' "tanks 1 and 2 are spaced, as shown, and held in such position by a central support 5, which is provided at its opposite ends with rectangular open frames 6. The open frames 6 are disposed between the adjacent open sides of the tank sections, such tank sections being provided at their open sides -with rectangular flanges 7, which are secured to the open frames G by means of bolts 8. Connected with the open .frames 6 are outstanding ears .9, having connection with webs 10. These outstanding ears are provided with openings 11, for the reception of screws or bolts whereby the central support may be secured to a vehicle or any otherA supporting structure. 'Theupper and lower tanks 1 and 2 have communication by means 70 of a plurality of curved pipes 12, which are disposed upon opposite sides of said tanks and connected therewith in any suitable manner. These curved pipes are spaced to permit air to travel radially between the same. e

T he central support 5 is provided midway its ends with an inwardly extending horizontal. sleeve 13, which holds a tulmlar bearing` 1-l, through which is journaled a rotaV80 tableshaft 15. Rigidly mounted upon the inner end of this shaft is a rotary blower or fan, which may be of any well known or preferred type. I have shown this blower as comprising a pair of spaced rings 1G, be- 35 tween and to which are secured blades 17. rl `he rings 1G are rigidly connected by spaced pins 18, which are connected with spokes 19, having rigid connection with the inner end of the shaft l5. The shaft 15 receives 90 its rotation from a pulley 2()` rigidly mounted thereon. The upper and lower tanks l and 2 are disposed dia-metrically with rela'- tion to the shaft 15 and the curved pipes 12 extend concentrically with relation to said shaft. The pipes 12 are retained in their requisite position by radially disposed plates or spaces 21, having openings formed therethrough for the reception of said pipes. Upon opposite sides of the pipes 12 are dis- 100 posed plates 22, serving to prevent the lateral escape of air discharge from the fan or blower. These plates are provided centrally thereof with openings 23, throughwhich air is drawnlto the fan or blower. The plates 22 are suitably connected With the tanks 1 and 2 and the spaces 21.

The tanks 1 and 2 are provided respectively with nipples 24 and 25. The circulatingtluid to be cooled is preferably introduced through the nipple 24 and withdrawn through the nipple 25. The upper tank is 1 also provided with a nipple 27 in ordei` that the cooling medium may be replenished when necessary.

In the operation of the cooling apparatus, the same is first illed with a cooling medium introduced through lthe nipple 24. This cooling medium is then. set in circula tion, the same being Withdrawn through the nipple and introduced into the upper tank through the nipple 24. The` rotatable fan or blower is now set in operation, to force air radially between and about the pipes l The circulating cooling medium, the same now having absorbed heat, passes from the upper tank to 'the lower tank through the curved pipes l2. While thus passing through these curved pipes, the heat contained in the cooling medium is transmitted to said pipes, which are cooled by the current of air passing thereabout. It is thus seen that the cooling medium is introduced in its heated condition in the upper tank and Withdrawn after being cooled from the lower tank. l

I Wish it understood that the form of my invention herewith shown and described is to be taken as a preferred example of the same, and that certain changes in the shape,

Having thus described my invention, Il

claim In apparatus of the character described, a diametrically arranged support adapted to be attached near its opposite ends to an automobile or the like, said support comprising an intermediate bodyT portion carrying at its end open frames, pairs of tank sections having their inner sides formed open and placed upon opposite sides of and in engagement with the open frames, bolts for detachably securing the tank sections to the open frames, a shaft journaled through said intermediate body portion, a fan carried by said shaft, and conduits disposed upon o posite sides of the fan and having their en s
